The following code sample demonstrates how to create a dynamic QR code that points to this documentation page with our logo. The destination URL can be changed without altering the actual QR code image. Additionally, you can track how many times the QR code has been scanned.
. Replace <YourApiKey> with the actual API Key you received during the sign-up process.
var client = new RestClient("https://qrcode-aws.silverlining.cloud/dynamic/create");
client.Timeout = -1;

Console.WriteLine(response.Content);This API Playground for our QR Code API allows you to generate custom QR codes in real-time. Simply input the content you'd like encoded, along with any optional parameters such as size or color, and receive a QR code directly from the API. Whether you're integrating QR code generation into your application or just experimenting with different configurations, the playground offers a user-friendly interface for instant results.
"To see the result, please send a request to the API."

"fill_color": STRING,

"error_correction": STRING,
"border": NUMBER,

}
Required
"content": The content to be represented in the QR code.
Optional
"background_color": The background color of the QR code in RGB hex format, preceded by a # (e.g., #4D4D4E). Default is white.
"fill_color": The color of the QR code tiles in RGB hex format, preceded by a # (e.g., #EDEDED). Default is black.
"image_url": A link to a publicly available image that will be placed at the center of the QR code.
"error_correction": Defines the error correction capability of the QR code, ensuring it remains readable even if slightly damaged or obscured. Acceptable values are "Low" (7% of codewords can be restored), "Medium" (15% of codewords can be restored), "Quartile" (25% of codewords can be restored), and "High" (30% of codewords can be restored). Higher error correction levels produce denser QR codes. The default value is "Low".
"border": Specifies the width of the QR code's border filled with the background_colour. Default value is 4.
"box_size": Determines the size of each individual box within the QR code grid, adjusting the overall QR code scale. Default value is 10.
"return_as_file": This parameter controls the format in which the QR Code is delivered. When set to `true`, the API will return the QR Code as a downloadable image file, providing immediate access to the QR Code in a ready-to-use format. In contrast, if set to `false` (or not specified), the API will return a URL pointing to the image of the QR Code, requiring an additional step to access the image file.
